(B) 8%
(C) 27%
(D) 15%

Answer 1

☯GIVEN :

• New Price= 207 dollars

• Old Price = 180 dollars

☯TO FIND :

• Increase Percentage.

➲SOLUTION :

✞To find an increase we have to subtract Old Price from New Price :

$\longrightarrow{ \sf{Increase =New \: Price - Old \: Price }}$

$\longrightarrow{ \sf{Increase = 207 - 180}}$

$\implies{ \underline{ \boxed {\bf{Increase = 27 \: dollars}}}}$

✞Now, Finding Increase Percentage :

$: \implies \sf{Increase\% = \: \dfrac{Increase}{Old Price} \times 100}$

$: \implies\sf{Increase\% = \: \dfrac{ \cancel{27}}{\cancel{180}} \times \cancel{100}}$

$: \implies\sf{Increase\% = 3 \times 5}$

$: \implies \underline{\boxed{ \pink{\bf{Increase\% = 15\%} }}}$

$\huge{ \purple{\therefore}}$Increase Percentage = 15%.

Answer 2

Answer:15%

Step-by-step explanation:

First, do the old price by the new price which is 207-180 and that equals 27. Then we put that over 180. Now we have 27/180 and that as a decimal is .15 so now we convert to a percent (x100) and we have the answer.
